Goku, the first to achieve Super Saiyan levels in Dragon Ball, has seen many Saiyans reach higher levels. Originally, Super Saiyan was a spectacle, but now it has evolved into multiple forms across timelines. The Super Saiyan forms increase raw power and combat abilities, with each transformation offering a unique look and strength. From False Super Saiyan to Ultra Instinct, Saiyans have unlocked various powerful forms. Super Saiyan Full Power proved efficient, while Ascended Super Saiyan was slower but stronger. Legendary Super Saiyan and its upgrade, Berserker Super Saiyan, are some of the strongest forms. Super Saiyan God and its evolution, Super Saiyan Blue, revolutionized the Saiyan forms. True Ultra Instinct and Ultra Ego have become the most powerful forms for Goku and Vegeta, showcasing their peak strength and evolution.
